We don't run a 3-4 all the time anyhow. In fact, anymore, 3-4 teams run that as a base defense, but then run all sorts of different defenses throughout the game. In passing situations with 3rd and 5 or longer, which is a lot of the time, you put Hali at end and rush the passer with Jordan and Houston, or you run a 4-3 with Jordan and Houston as OLB that can blitz.
